SYSTEM CONFIGURATION When the CHANNEL ADJUST menu first appears the test tone is off. If desired, you may immediately use the ⁄/¤ Navigation Button n to select any channel for adjustment using an external source, such as a test disc, from which to judge the output levels. After the › cursor is pointing to the channel to be adjusted, press the ‹/› Navigation Button o to raise or lower the output level. However, before proceeding with any manual adjustment we recommend that you first use the AVR's internal test tone generator and automatic sequencer to send a tone to each channel so that you may verify that all speaker connections have been properly made. To turn the test tone on and have it automatically circulate among the channels where a speaker has previously been configured (see page 20), press the ⁄/¤ Navigation Button n until the › cursor is pointing to the TEST TONE line on the menu. Next, press the ‹/› Navigation Button o until AUTO SEQ is shown in highlighted video. At this time the test tone will immediately begin to circulate clockwise around the room, playing for two seconds in each speaker before switching to the next speaker position. The › cursor will blink next to the active speaker to indicate which speaker the sound should be coming from. As the test noise circulates, listen to make certain that the sound comes from the speaker position shown in the Lower Display Line T. If the sound from a speaker location does NOT match the position indicated in the display, turn the AVR 235 off using the Main Power Switch 1 and check the speaker wiring or connections to external power amplifiers to make certain that each speaker is connected to the correct output terminal. After checking for speaker placement, let the test noise circulate again, and listen to see which channels sound louder than the others. Using the front left speaker as a reference, press the ‹/› Navigation Button o to bring all speakers to the same volume level. When the ‹/› Navigation Button o is pushed, the test noise circulation will pause on the channel being adjusted to give you time to make the adjustment. When you release the button, the circulation will resume after five seconds. Continue to adjust the individual channels until the volume level sounds the same from each speaker. Adjustments should be made with the ‹/› Navigation Button n only, NOT the main volume controls. If you are using a sound-pressure level (SPL) meter for precise level adjustment, set the volume so that the meter reads 75dB on the C-Weighting, Slow Scale. You may also make these same adjustments with complete manual control over the channel being adjusted by pressing the ⁄/¤ Navigation Button n until the › cursor is pointing to the TEST TONE SEQ line on the menu and then using the ‹/› Navigation Button o to select MANUAL in the highlighted video. In the MANUAL mode, the test tone will also start immediately, but the tone will only be moved to another channel by pressing the ⁄/¤ Navigation Button o. When the manual sequencing mode is active, the tone is turned off by pressing the ⁄/¤ Navigation Button o until the › cursor is pointing to the TEST TONE line and the ‹/› Navigation Button o is then pressed to select OFF. Using the Semi-OSD System The output levels may also be adjusted at any time using the remote control and semi-OSD system. To adjust the output levels in this fashion, press the Test Button i. As soon as the button is pressed, the test tone will begin to circulate as indicated earlier. The correct channel from which the test noise should be heard will be shown in the lower third of the video screen and in the Lower Display Line ¯. While the test noise is circulating, the proper channel position will also be indicated in the Speaker/ Channel Input Indicators ˆ by a blinking letter within the correct channel. To adjust the output level, press the ⁄/¤ Buttons n until the desired level is shown in the display or on-screen. Once the buttons are released, the test noise will begin to circulate again in five seconds. When all channels have the same output level, press the Test Button i again to complete the process. If you find that the output levels are either uncomfortably low or high, you may repeat the procedure, but first adjust the master volume either slightly higher or lower (but not higher than 0dB) to compensate. Do not adjust the volume during the procedure, as that will cause the output levels to be higher or lower for only some channels, resulting in uneven balance. To make channel level adjustments to an external source, rather than using the AVR's internal test tone, simply press the Channel Select Button m, and each individual channel and its level offset will be displayed on-screen in the semi-OSD display. This is the equivalent of using the CHANNEL ADJUST menu with the test tone set to OFF. NOTE: Output level adjustment is not available for the VMAx or Surround Off modes. Additional Input Adjustments After one input has been adjusted for Surround mode, digital input (if any), speaker type and output levels, go back to the INPUT SETUP line on the MASTER MENU (Figure 1) and enter the settings for each input that you will use. In most cases, only the digital input and surround mode will be different from one input to the next, while the speaker type, Night mode and output level settings will usually be the same and may be quickly entered by entering the same data used for the original input. When all settings and adjustments have been made, press the OSD Button v to return to normal operation of the AVR. Once the settings outlined on the previous pages have been made, the AVR 235 is ready for operation. While there are some additional settings to be made, these are best done after you have had an opportunity to listen to a variety of sources and different kinds of program material. These advanced settings are described on pages 32 and 33 of this manual. In addition, any of the settings made in the initial configuration of the unit may be changed at any time. As you add new or different sources or speakers, or if you wish to change a setting to better reflect your listening taste, simply follow the instructions for changing the settings for that parameter as shown in this section. Having completed the setup and configuration process for your AVR 235, you are about to experience the finest in music and home theater listening. Enjoy! 24 SYSTEM CONFIGURATION
